Preheat your oven to 325°F.
Season the short ribs generously with salt, pepper, garlic powder, and dried thyme.
In a heavy, oven-safe pot or Dutch oven, sear the short ribs on all sides over medium-high heat until browned; this helps develop deep flavor.
Add a small amount of water or broth if desired (optional, not listed in macros) and cover the pot. Transfer to the oven and braise for about 2 to 2.5 hours until the meat is fork-tender.
While the short ribs are braising, preheat a separate oven tray at 400°F. Peel and chop the carrot and parsnip into evenly sized pieces.
Toss the vegetables with olive oil, a pinch of salt, pepper, and a sprinkle more of garlic powder and thyme.
Roast the vegetables in the 400°F oven for about 25-30 minutes until tender and slightly caramelized.
Plate a serving of the braised short ribs alongside a generous portion of the roasted vegetables, and enjoy your richly flavored, balanced meal.
